If the measured value is not within the specified value, inspect the suspension parts for damage and/or wear and replace them if necessary because camber is not adjustable.
ADJUST CAMBER AND TOE-IN
1. Measure the distance from the LH lower suspension arm bracket set bolt to the RH axle carrier rear side set bolt as shown in Fig 4 .
2. Measure the distance from the RH lower suspension arm bracket set bolt to the LH axle carrier rear side set bolt as shown in Fig 4 .

  Length difference: 6.0 mm (0.236 in.) or less
3. Loosen the upper and lower suspension arm adjusting cam set nuts.
4. Adjust the camber and toe-in by turning the adjusting cams.

6. How to read adjusting chart (using examples).
  1. Measure the present alignment.
    1. Example:
      1. Camber (RH): +0°01' (+0.02°)
      2. Camber (LH): -1°29' (-1.48°)
      3. Toe-in (total): IN 6.0 mm (0.236 in.)
  2. Mark the difference between the standard value (A) and the measured value (B) on the adjustment chart.
    1. Standard value:
      1. Camber: -0°44' (-0.73°)
      2. Toe-in (total): IN 2.0 mm (0.079 in.)
      3. Formula: A - B = C
      4. Camber: (RH): -0°44' - (+0°01') = -0°45'
      5. Camber: (LH): -0°44' - (-1°29') = 0°45'
      6. Toe-in (total): IN 2.0 - IN 6.0 = OUT 4.0
      7. Toe-in (each side): OUT 2.0

  3. As shown in the example chart, read the distance from the marked point to center of the chart, and adjust the upper and/or lower arm adjusting cams accordingly.
    1. Amount to turn adjusting cams (by graduation):
      1. Upper arm cam (RH): + (Inward) 3.2
      2. Lower arm cam (RH): + (Inward) 0.8
      3. Upper arm cam (LH): - (Outward) 2.3
      4. Lower arm cam (LH): + (Inward) 1.0
